He told BBC Radio Scotland's The Kaye Adams programme: "Nobody expected it to happen. Everybody was clapping and cheering for him.

"He was hilarious, especially his pointing and his dance moves. The other policemen were standing and clapping and cheering. Not sure if he was their boss but when they first saw him it was like their dad had just got up on the karaoke."

Ch Insp Mark Sutherland, of Police Scotland, said the sergeant's performance helped to defuse any simmering tensions in the pub.

"I was pleased to see that once the incident had been professionally concluded, my officers were able to share a lighter moment with those who remained in the pub," he added.
